The climate crisis and all the evil in the world drives me to despair

According to science we have passed a stage in global climate change, we have not passed THE stage. Unless my information is wrong. We can still turn things back towards good, we just may not be able to reverse the damage we will have already started.

Barring some new technology, of course. What we can do now is wholly dictated by our current understanding. I feel it is important to remember that this understanding may change.
